Video, pictures of 'Potter' stars at Queen's birthday party

The Children's Party to celebrate Queen Elizabeth’s 80th birthday took place today and in attendance were author JK Rowling and actors Rupert Grint and Matthew Lewis. While Jo read from Harry Potter and the Half-Blood Prince, a video featuring Dan, Rupert, Emma and Matthew was shown as part of the skit for the search for the Queen’s handbag.

UPDATE: Thanks to MuggleNet you can see a picture here of Emma and Rupert sitting in front of the Queen.

UPDATE II: JK Rowling commented from the event that she is sad that the Harry Potter saga is coming to an end and when pressed for a publication date for the last book said:

I'm doing well I think. You can never really tell till you get near the end. I am not quite there yet.
